Introducing Intel's Smallest Processor: A New Miracle in Miniaturization

Introducing the Intel® Atom™ Processor

Intel's smallest chip. Built with the world's smallest transistors¹.

The 45nm Intel Atom processor is a tiny sliver of silicon "This is our smallest processor built with the world's smallest transistors. The Intel Atom processor is based on an entirely new design, built for low power and designed specifically for a new wave of Mobile Internet Devices and simple, low-cost PC's. This small wonder is a fundamental new shift in design, small yet powerful enough to enable a big Internet experience on these new devices. We believe it will unleash new innovation across the industry."


– Intel Executive Vice President Sean Maloney

As Intel's smallest and lowest power processor², the Intel® Atom™ processor will enable the industry to create pocket-sized and low power Mobile Internet Devices (MIDs), and Internet-focused notebooks (netbooks) and desktops (nettops).


Newly designed from the ground up and packing an astounding 47 million transistors, the 45nm Intel Atom processor is a tiny sliver of silicon—yet still delivers the power and performance you need for full Internet capabilities.+


  • Get a new range of power-efficient devices with excellent performance enabled by all new hafnium-infused 45nm high-k silicon technology
  • Extend battery life in some devices with an incredibly low idle power as low as 30 mW allowing the device to stay powered on while also conserving energy

Powering the next generation of Internet-centric devices, Intel Atom processors will power the latest in pocketable, portable devices. Intel devices powered by Intel Atom processors allow you to stay in touch on-the-go—connect to business and enjoy entertainment—remain connected affordably with a new series of netbooks and nettops—and so much more.
